ECE 418: Algorithms of Circuit Design Quiz 6

Assume the transconductance parameters for nMOS and pMOS transistors to be equal to gm and gd. Also assume that the parasitic capacitances for each transistors as Cgs (gate-to-source capacitance) and Cgd (gate-to-drain capacitance).

1. Assume Vp is constant in Figure (a), what is the low-frequency gain : [2points]

2. How many poles does the amplifier in (a) have ? [2 points]

3. Find the location of the poles in (a) ? [3 points ]

4. Does the circuit in (b) has a lower or greater high frequency gain than (a) ? Explain why ? [ 3 points ]
